Abstract

PURPOSE:To improve general capacity efficiency of a three-dimensional warehouse facility greatly and make transfer of cargo efficient. CONSTITUTION:A three-dimensional warehouse 10 has multi-step shelves 26 in the vertical direction, and this shelf (one step) is formed by bars 28 which are shaped like comb teeth and provided apart in the direction of width of the three-dimensional warehouse 10. A support section 40 of a stacker crane 12 can travel in the direction of width of the three-dimensional warehouse 10 and move vertically. The support section 10 is formed by arms 36 which are shaped like comb teeth and face reverse to the shelves 26. The support section 10 can travel between shelves and travel in the vertical direction which crosses the shelves 26 without interfering with the shelves 26. Consequently, storage of cut plate (cargo) S is achieved by traveling the support section 40 in space between shelves horizontally by supporting the cut plate S in the support section 40 and lowering the support section 40 (vertical travel) at the predetermined position. Discharge of the cut plate is achieved by the reverse procedure.

Description

[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention relates to a multi-level warehouse facility equipped with shelves for storing loads and a stacker crane for transferring loads to and from the shelves, and in particular, the storage of cut plates, wire rods, etc. is simplified. This invention relates to a three-dimensional warehouse facility with high volumetric efficiency that can easily store, transfer, and receive flattened cargo.

0002

[Prior art] At steelworks, cut sheets of manufactured thin steel plates are
Temporary storage is performed for testing and processing.

[0003] As a warehouse for storing and storing loads such as the above-mentioned cut boards, for example, Japanese Patent Laid-Open No. 60-128102 and 1986
3-272704, JP 1-294101, JP 2-9
5607 and the like are known.

[0004] These warehouses are composed of stacker cranes used to transfer cargo and three-dimensional shelves for storing cargo, which are arranged parallel to the running direction of the stacker cranes. The transfer of cargo between the two is carried out by moving the cargo between the two using other conveyance means.

[0005] Therefore, in the conventional warehouse described above, in addition to the parallel drive means for moving the stacker crane along the shelves, a separate orthogonal drive means is required for moving the load between the stacker crane and the shelves. be.

[0006] Therefore, the work of delivering and receiving loads to and from the shelves consists of two stages: a parallel conveyance operation in which the loads are placed on the stacker crane and moved along the shelves, and an orthogonal conveyance operation in which the loads are moved between the stacker crane and the shelves. Therefore, it has the disadvantage that it takes a lot of time.

[0007] In addition to this drawback, since the entire stacker crane moves in parallel in front of the shelves, the running space of the stacker crane is large, and the volumetric efficiency is correspondingly low. In particular, when storing thin objects such as cutting boards one by one, the volumetric efficiency becomes even lower.

An example of improved volumetric efficiency is the warehouse disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2-95607. This reduces storage space by storing plate-shaped materials vertically in slit-shaped storage shelves with a width slightly wider than the maximum plate thickness.

[0009]

Problem to be Solved by the Invention However, the warehouse (storage device) disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2-95607
Although storage space efficiency has been improved, the running space of stacker cranes is still large, and space-consuming devices such as containers are required to load and unload cargo, so the volumetric efficiency of the warehouse as a whole is decreasing. The problem is that it has not been sufficiently improved.

The present invention has been made in order to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a multi-level warehouse facility in which overall volumetric efficiency is greatly improved and in addition, cargo can be transferred and received efficiently. The task is to

[0011]

[Means for Solving the Problems] The present invention provides a multi-story warehouse facility that includes a multi-story warehouse having shelves for storing cargo, and a stacker crane having a support section for transferring cargo to and from the multi-story warehouse. In the above, the supporting part of the stacker crane is formed of a plurality of spaced apart arms, and the supporting part of the stacker crane is horizontally movable along the shelf surface of the multi-story warehouse and interferes with the shelf. The above-mentioned problem has been achieved by allowing vertical movement across the shelf surface without any movement.

0012

[Function] In the present invention, when moving the stacker crane for delivering and receiving cargo to and from the multi-story warehouse in the width direction along the entrance/exit end of the multi-story warehouse, the support part of the stacker crane is moved from the shelf surface. Since the support part of the stacker crane can be moved horizontally along the shelf, and the support part of the stacker crane can be moved vertically without interfering with the shelf, the support part of the stacker crane supporting the load can be moved horizontally. Therefore, when there are multiple shelves, the load can be transported between the shelves to be carried in to any position in the horizontal direction, or carried out from any position.

[0013] Furthermore, since the supporting part of the stacker crane can be moved vertically without interfering with the shelves,
Loading and unloading (giving and receiving) loads to and from shelves at arbitrary positions can be done simply by moving the stacker crane support in two directions, horizontal and vertical. Since there is no need to use other transport means, the process can be carried out in an extremely short time.

[0014] In this way, when transferring cargo to and from shelves at arbitrary positions in a multi-level warehouse, the cargo storage space is commonly used as the transfer space by transferring the cargo along the shelf surface. This makes it possible to significantly reduce the running space of the stacker crane. At the same time, by making the shelves multi-tiered, it is possible to store a large number of thin objects, thereby increasing the storage density of the objects.

As described above, according to the present invention, the overall volumetric efficiency of the multi-level warehouse facility can be greatly improved, and moreover, it has become possible to transfer cargo efficiently.

FIG. 4 is a schematic explanatory diagram showing a state in which cut boards are stored on shelves of a multi-story warehouse provided in the multi-story warehouse facility. Further, FIG. 5 is a schematic front view showing an enlarged view of a stacker crane included in the multi-story warehouse facility, and FIGS. 6 and 7 are partial side views showing an enlarged main part of the stacker crane, respectively.

The three-dimensional warehouse facility of this embodiment includes a three-dimensional warehouse 10 in which shelves for storing goods are provided in multiple stages, and a front end (input/output end) 10A of the three-dimensional warehouse 10 on the side where goods are loaded into and taken out from the shelves.
It is equipped with a stacker crane 12 that moves in the width direction along It is provided with a payout table 16 that receives from the stacker crane 12 when stacking.

The multi-story warehouse 10 has a back support 20 whose lower end is fixed to a base 18, and a front support 2 opposite thereto.
2 and a beam 24 suspended from the upper ends of both support columns 20 and 22, an outer peripheral skeleton is formed.

The multi-level warehouse 10 is provided with multi-level shelves 26 in the vertical direction, one end of which is fixed to the back support 20 located at the back of the shelf 26,
It is formed by a bar 28 extending in the A direction. this bar 2
A plurality of bars 8 are arranged in a comb-like shape at predetermined intervals in the width direction of the shelf, and one shelf is formed by the comb-like bars 28 arranged in the width direction in this way. That is, the shelves of the three-dimensional warehouse 10 are formed by further arranging the bars arranged in multiple rows in multiple stages.

In the multi-story warehouse 10, when storing one cut board S on the shelf 26, as shown in FIG.
The cut plate S is placed over 8 hours.

FIG. 4 shows a state in which one cut plate S is stored on the above-mentioned shelf 26, as viewed from the direction of the entrance/exit end 10A of the multi-story warehouse 10.

On the other hand, the stacker crane 12 has a bogie frame 30 and a pair of support frames 32 erected at the front end thereof. An extending ball screw 34 is disposed, and the ball screw 34
A ball nut 38 fixed to the center of the support frame 36 is integrated into the support frame 36, and the support frame 36 moves up and down in accordance with the rotation of the ball screw 34 (FIGS. 5 and 7).
).

A plurality of arms 38 extending from the front to the rear of the multi-story warehouse 10 are fixed to the support frame 36, and these arms 38 are attached to the support portion 4 of the stacker crane 12.
0 and can be loaded with cargo.

A plurality of arms 3 constituting the support section 40
Although the extending directions are opposite to each other, the bars 8 are arranged in a comb-like shape with the same spacing as the bars 28 constituting the shelves 26 of the multi-story warehouse 10.

Therefore, when this support section 40 moves (vertically moves) in a direction perpendicular to the shelf surface (the surface formed by the horizontally arranged bars 28), as shown by the two-dot chain line in FIG. It can be moved without interfering with the shelf 26. That is, the support section 40 can be moved in the direction intersecting the shelf 26 without the arm 38 hitting the bar 28.

The stacker crane 12 is installed on rails 44 laid on a traveling base 42 on the floor, and is movable on the rails 44 in the width direction of the multi-story warehouse 10. At that time, the trolley frame 30 is
It moves at a position lower than the lowest shelf 26'.

The movement of the stacker crane 12 is achieved by engaging the rotational power of the travel motor 46 attached to the lower end of the stacker crane with the rack 46 disposed parallel to the rail 44 below the bogie frame 30. This is done by transmitting the signal to gear 48.

Further, the support section 40 of the stacker crane 12 transmits the power of the lifting motor 50 attached to its upper end to the ball screw 34 via the chain wheels 52, 54 and the belt 56. Vertical movement is possible by rotating the screw 34.

Next, the operation of this embodiment will be explained.

When the cut boards S are carried into the multi-level warehouse 10 and stored on the shelves 26 at predetermined positions, the stacker crane 12 is aligned with the loading table 14 as shown in FIGS. 1 and 2. Like the shelf 26 described above, the loading table 14 is formed in a comb-like shape that does not interfere with the support section 40 of the stacker crane 12.

[0032] The stacker crane 12 is mounted on the loading table 14.
On the other hand, by arranging the planar view as shown in FIG. (not shown) is supported by the support section 40 and lifted.

At this time, in order to transport the cutting board S safely and reliably, as shown in FIG.
0 to press and fix the cutting plate S.

Next, the stacker crane 12 is raised to the height of the shelf 26A to be stored, and then moved in the width direction of the multi-storey warehouse 10 at that position, thereby separating the shelf 26A and the shelf one step above. In the space between 26B,
The support section 40 supporting the cutting board S is moved (horizontally moved) along the shelf surface. After horizontally moving the supporting part 40 to a predetermined position, the holding member 60 is removed, the stacker crane is lowered, and the supporting part 40 is connected to the target shelf 26A without interfering with the shelf 26A. Move it (vertically move) to the space between it and 26C one step below.

As a result, the cutting board S carried in while being supported by the support section 40 is stored at a predetermined position on the shelf 26A. Next, the stacker crane 12, whose support part 40 has been moved between the shelves 26A and 26C, is horizontally moved in the opposite direction, lowered, and returned to the loading table 14 again.

[0036] Thereafter, by repeating the same operation, the cut plates S can be stored one after another on the shelves 26 at desired positions.

[0037] When returning the stacker crane 12 to the loading table 14 after storing the cut plates S, if there is no load such as cut plates stored on the shelf below the shelf 26C, the stacker The crane 12 can be lowered to a predetermined position, for example, to a position lower than the lowest shelf 26', and then horizontally moved to similarly lower the loading platform 14.
You can also change it back to .

On the other hand, when the cutting boards S stored in the multi-level warehouse 10 are to be carried out and discharged, the operations described above may be reversed to the carrying-in and storage operations.

In the case of discharging the cut plate S stored on the shelf 26A above, the stacker crane 12 is moved and its support part 40 is placed below the cut plate S in the space between the shelves 26A and 26C. to be located.

Next, the stacker crane 12 is raised to support the cutting board S on the support section 40, and at the same time move the support section 40 into the space between the shelves 26A and 26B (vertical movement). The stacker crane 12 is moved to the unloading platform 1
6, and the supporting portion 40 is horizontally moved in the space along the shelf surface.

After the stacker crane 12 is aligned with the payout table 16 as shown by the two-dot chain line in FIG. By setting the position lower than the placing surface, the cut plate S can be delivered to the delivery table 16.

[0042] The above-mentioned dispensing stand 16 is similar to the above-mentioned taking-in stand 14.
is substantially the same as. Therefore, here, the cutting board S is transferred from the loading table 14 to the support section 40 of the stacker crane 12.
By performing the reverse operation of taking in the cut plate S, the cut plate S can be delivered.

[0043] Furthermore, it is not necessarily necessary to separately provide the loading table 14 and the dispensing table 16; for example, if the dispensing table 16 is not provided,
The loading table 14 may also be used as a dispensing table.

As mentioned above, according to this embodiment, the cut plate S is
The stacker crane 12 is moved along the width direction of the multi-story warehouse because it is possible to carry it into the multi-storey warehouse 10 and take it out from the multi-storey warehouse 10 by using the space (storage space) between the shelves. The travel path (traveling area) required for this can be significantly reduced.

Furthermore, the multi-dimensional warehouse 10 can store the cut plates S at extremely high density. Therefore, the three-dimensional warehouse facility of this embodiment can significantly improve the volumetric efficiency as a whole.

Furthermore, since the support section 40 is movable horizontally along the shelf surface and vertically movable across the shelf surface, it is possible to move the support section 40 horizontally along the shelf surface and vertically across the shelf surface. The shelves 26 can be placed at any position in the multi-story warehouse 10 without having to move cutting boards between shelves (warehouses).
In contrast, cutting plates can be delivered and received easily and quickly.

Although the present invention has been specifically explained above, the present invention is not limited to what has been shown in the above embodiments.

For example, the shelves of a multi-story warehouse are shown to be formed of comb-like bars, and the support parts of stacker cranes are similarly formed of comb-like arms. The specific shape of the shelf and the support part is not limited to this, but the support part can move vertically without interfering with the shelf and can also move horizontally when the stacker crane is moved up and down. It can be made into various shapes as long as it can be made.

Further, the arm constituting the support portion of the stacker crane is not limited to a straight arm, but may be U-shaped when viewed from the side, and may have a concave central portion. Similarly, the bars constituting the shelf may also be U-shaped when viewed from the side.

Furthermore, the load is not limited to the cut plates described above, but includes rods and wire rods, and is not particularly limited as long as it can be stored in a substantially flat state.

[0051]
